| Abstract: |
An integral part of the ALMA system is to process astronomical data offline. Such data reductions are often broken up into discrete units of processing called tasks. While the ALMA system will provide many typical offline tasks out of the box, the ability to easily add new tasks which perform data reductions currently unforeseen by ALMA developers is crucial. It is therefore important that the ALMA Common Software (ACS) provide a mechanism for quickly and easily creating offline data analysis tasks. The mechanism which ACS has implemented includes a set of XML schemas supporting the description of tasks and an Application Programmer's Interface (API) which offline task developers can use to quickly integrate data reduction logic into the ALMA system with minimal additional programming effort beyond that of coding the actual data reduction algorithms. This paper presents the status of offline data processing support in ACS, including mechanisms for defining and implementing data reduction tasks. Future enhancements and extensions will also be discussed. |
